Problems solved by technology

When the traditional cold extrusion molding process is used to process bimetallic composite materials, the blank is subjected to three-dimensional compressive stress in the mold to deform the material, and the metal flow of the material is poor, which will cause serious "lag" flow phenomenon and affect the processing quality of the product.

Abstract

The cold extrusion device comprises an extrusion device body and a control device, an extrusion forming die is installed on the extrusion device body, a plurality of extrusion holes are longitudinally formed in the extrusion forming die, and the control device is connected with the extrusion forming die. And each extrusion hole is sleeved with an ultrasonic vibration ring. According to the invention, uniform and consistent dynamic balance of flowing speeds of profiles in all extrusion cavities can be realized, and all radiating fins of a radiator after extrusion are uniform in density and consistent in length. Due to the fact that the metal flowing condition is improved through ultrasonic vibration, the extrusion speed of the profile is adjusted, the subsequent processing procedure completed through extrusion of the radiator is omitted, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of cold extrusion processing technology, in particular to an ultrasonic cold extrusion device for bimetal composite materials. Background technique [0002] With the development of modern science and technology and modern industry, it is difficult for a single metal to fully meet the requirements of its comprehensive properties of materials. Therefore, in recent years, new bimetallic composite materials have received widespread attention from all over the world. Bimetallic composite material is a layered composite material prepared by metallurgical bonding of two materials with different physical, chemical and mechanical properties at the interface by the method of composite molding. This composite method maintains the original composition on both sides of the interface, and produces metallurgical bonding of the transition layer at the interface, so that the composite material has the "composite effect" of...
